About the Wazau MMS Molten Metal Splash Tester
The MMS from Wazau (Dr.-Ing. Georg Wazau Mess- + Prüfsysteme GmbH, Berlin, Germany) determines the resistance of materials to liquid metal splashes on protective clothing, to DIN EN ISO 9185.
The materials test involves pouring defined amounts of molten metal onto the specimen, which is held at an angle to the horizontal on a mounting frame. Damage is assessed by placing a PVC foil directly behind and in contact with the specimen and noting the changes in the PVC foil after casting. Depending on the result, the test is repeated using a larger or smaller amount of metal until the minimum amount causing damage to the PVC film is determined.
The molten metal is melted in a crucible using a high-frequency induction furnace. A high-performance glass fiber ratio pyrometer provides the reference variable for temperature control by determining the pouring temperature. The temperature of the melt is set and controlled from 700 to 1800 °C by a temperature controller, and the tilting speed and tilting angle are controlled and adjusted via a stepper motor.

Molten metal splash tester: frequently asked questions
Which standard does the Wazau MMS follow?
DIN EN ISO 9185, the determination of the resistance of materials to liquid metal splashes on protective clothing. A calibration device to DIN EN ISO 9185 is part of the delivery.
How is damage assessed?
A PVC foil is placed directly behind and in contact with the specimen. After the molten metal is poured, the changes in the PVC foil are noted. The test is repeated with a larger or smaller amount of metal until the minimum amount causing damage to the PVC foil is found.
What temperature range does the furnace cover?
The molten metal is melted in a crucible in a high-frequency induction furnace. The temperature of the melt is set and controlled from 700 to 1800 °C by a temperature controller, with a high-performance glass fiber ratio pyrometer determining the pouring temperature.
How is the pour controlled?
The tilting speed and tilting angle are controlled and adjusted via a stepper motor, using an electrical tilt mechanism that is electronically controlled. The test bench has an integrated PC with touchscreen.
What is supplied with the tester?
The test bench with integrated PC and touchscreen, induction furnace, specimen holder, crucible tongs with coupling, crucibles, electrical tilt mechanism, pyrometer, calibration device, sand tray, specimen stencil, foot switch, software, operating manual and fireproof protective equipment (hand protection, protective mask, apron and gaiters).
What must the customer provide?
A water drain with a sufficient sink, an exhaust system (mandatory for tests with cryolite), PVC foil, a balance up to 1000 g with ± 1 g accuracy, and a muffle furnace for PVC foil calibration.
What are the installation requirements?
A 3~ 400 VAC, 50/60 Hz, 6 kVA supply and water. The tester measures approx. 1270 × 875 × 1550 mm (W × D × H) and weighs approx. 260 kg. Dimensions may vary as the product is further developed.
